Solutions for Book Scanning

The digitization of bound materials such as books, magazines, journals, and newspapers is especially demanding. It requires a solution that delivers conservation handling, preservation image quality, production speed and extensive flexibility. DTDCH has several systems that meet these demands and are ideal for digitizing bound materials.

Conservation Handling

 

Bound materials require careful handling to ensure the process of digitization does not degrade their condition. This is especially important with tightly bound materials, delicate parchment, items with friable illuminations, and materials already in degraded condition. Each of our systems provides a range of handling options keeping the operator in control of the material, thereby ensuring their safety.

100° vs 180° Opening
All DTDCH systems support scanning bound materials open to 100°, minimizing tension on the binding and maximizing the per-page capture resolution. Most of our systems can also be configured to capture material opened to 180° which allows both pages to be captured simultaneously for a faster workflow (note that the BC100 only allows a 100° opening but uses two cameras and thereby maintains the same faster workflow).


PSI-Controlled Contact vs Non-Contact
Contact scanning uses a glass platen to reduce page curl. Our DT RGC180 and DT BC100 use purpose-built pneumatics to offset the weight of the glass platen. This puts the operator in complete control of how much pressure is applied to the materials in order to keep within safe limits for any given object.

Preservation Quality

DTDCH solutions exceed FADGI 4-Star and Metamorfoze-Strict standards. At the heart of all of our systems is a Phase One digital back that provides up to 100mp of resolution at 16 bits of color depth. Coupled with illumination with high spectral qualities, high resolution lenses, and ultra-low vibration shutters this results in true Preservation Digital Objects with accurate color, tone, and detail. Many manufacturers claim their equipment attains FADGI 4-star or ISO ISO 19264-1 A-class qualitybut very few others do. Leveraging Phase One’s raw processing with its class-leading debayering algorithm DTDCH solutions extract pixel level detail and color accuracy previously only seen in cumbersome multi-shot systems.

 

Production Speed

A collection of “only” a few thousand bound-materials can contain millions of pages. With such volume it is critical to maintain production speed in both the capture and post-processing stages.

Capture Stage
Our systems capture in a small fraction of a second and display almost immediately. The sophisticated material handling systems of the DT RGC180 and DT BC100 allow the operator to move through the material as quickly as they feel is safe. Therefore, the capture rate is only limited by the condition of the material and whether the system is capturing facing pages or each page individually.

Post-Processing Stage
DTDCH offers two excellent post processing suites.

Capture One CH 10 is a modern solution built on the venerable and widely used Capture One software. It is designed for cultural heritage workflows, supports all modern operating systems, is frequently updated, and can handle massive numbers of files with ease. Checking focus, zooming in on high resolution images, and scrolling through pages for quality control is lightning fast. Capture One CH 10 features book scanning tools such as Autocrop and AutoDeskew, Page Splitting,  LAB Support, Resolution Ruler, Batch Processing, and Raw-Stage Quality Control. These tools enable the automation of tedious post-production tasks that are inherent to the post-processing stage of book digitization. If your institution needs to OCR text, generate and quality control METS/ALTO metadata, or combine the individual pages to a PDF, our solutions integrate seamlessly with nearly any OCR and digital binding software such as CCS DocWorks Content Conversion Software.

Zeutschel OmniScan is a purpose-built Cultural Heritage scanning software with an extensive list of unique features specific to book scanning. Its patented Perfect Book technology provides deskew, book curve correction, page separation and thumb removal. Best of all OmniScan is very easy to use and can be picked up very quickly by new operators.

Extensive Flexibility

The encyclopedic collections of cultural heritage institutions are rarely homogenous. Our systems are versatile, interoperable, and modularly upgradeable to ensure you’re not stuck with a limited tool box. They are also flexible in their use, allowing techniques that are impossible on competing systems.

Interoperable and Modularly Upgradable
Our solutions for digitizing flat art comprise either an all-in-one format or a modular format. Our modular solutions for digitizing bound materials include a reprographics system (such as the DT BC100, DT RG3040, or DT RGC180), a camera head (such as the DT RCam), lighting, and in some cases, an optional book cradle. Each of these components can be purchased, traded in and upgraded separately. For instance, an institution that purchased a [DT RGC180 and DT RCam] for scanning newspapers would only need to add the DT Film Scanning Kit to scan an encyclopedic collection of transmissive materials. Our all-in-one solutions such as the Zeutschel ScanStudio provide upgradability by means of upgrading the Phase One digital back used for image capture

Big Books? No problem
Many historical collections include oversized bound material that are too large for most book scanners. The DT BC100 glass platen supports scanning pages up to 17” x 24“ with bindings up to 4”. The DT RGC180 can capture facing pages of up to 17” x 25” in the cradle, or individual pages up to 30”x40” using the included hard top. The DT RG3040 can accommodate facing pages of up to 14” x 10” using the optional book cradle or individual pages up to 30”x40” using the hard top. For increased versatility the DT RGC180 and DT RG3040 can accommodate massive bound materials of up to 54” x 70” pages in a single capture, or even larger by stitching by remounting the camera on the column to face backward. The Zeutschel ScanStudio can be used with two different cradles which can accommodate up to a 24” x 40” page size.

Creative Lighting
Most of the time Cultural Heritage imaging is done with very flat proscriptive lighting, typically two lights mounted 45° from the subject. However,  there are situations where more creative lighting is required, for instance, to rake light across an embossed cover to enhance the dimensionality of the embossing. DTDCH systems can provide this creative lighting. With the DT RGC180 and RG3040 the lights are always on light stands and can be easily raised or lowered without limitations. With the DT Atom the DT Photon lights can be removed from the fixed arms and placed on stands in any position. With the Zeutschel ScanStudio the lighting is on arms that can be rotated up or down for a higher or lower position within a fixed arc.
